We show that the partition functions of the higher genus B-model on the elliptic curve are almost holomorphic modular forms, which ... More
Rational Points on Del Pezzo Surface of degree 1 and 2Apr 22 2009Apr 25 2011We discuss the rational points on del Pezzo surface of degree 1 and 2 over any finite field $\mathbb F_q$, and give out the explicit equations of del Pezzo surfaces that have unique rational point.
Compression bounds for wreath productsJul 29 2009Dec 06 2009We show that if $G$ and $H$ are finitely generated groups whose Hilbert compression exponent is positive, then so is the Hilbert compression exponent of the wreath $G \wr H$. We also prove an analogous result for coarse embeddings of wreath products. ... More
